FreeBSD laptops wiki

I don't see that as some public database of working machines but more like developers experiences with particular machines. Many of them for the Dells are rather dated reviews compared to todays FreeBSD support. So it is more a snapshot in time of a developers interaction. What works OOB at the time. Guidelines of what might work for you. What to expect from a notebook desktop.
I did not mean to dissuade you from contributing.
Looks like you can sign up to get an wiki account here:

Another approach might be to ask an existing developer to help add your notebook details.
@wblock is a frequent contributor looking at the edits. I am sure he could help you.
